"By February 2012, less than a year after installation, I begin to have problems. So I called Mt Everest, and they come and fix things here and there, and I don't think much of it because other than the inconvenience of occasionally being too hot, it's not costing me too much money. =) Here are some of the receipts I could find... Mt. Everest - 2/16/12 - $194.12 Mt. Everest - 2/17/12 - $0.00 Mt. Everest - 2/18/12 - $0.00 --new company name-- Tiger - 1/22/13 - $210.00 (Became Club Member) Tiger - 8/16/13 - $0.00 Tiger - 5/16/14 - $0.00 (Waived/Warranty) Fast forward to October 2015, a little over four years after installation, I have a coolant leak somewhere that can't seem to get fixed, and Tiger has to keep recharging my "closed" system... the only difference is now I have to start paying for this service. (I guess Freon is expensive.) I start to panic because my family is undergoing financial hardships, and whatever money I once had went toward the air conditioner I purchased four years earlier. Thankfully, Tiger works with me on this, and I am grateful. However, they warn me that I will need to have the evaporator coils (???) changed out. EEEK! At this point, I am already $10,000 (plus) into this system, it is only four years old, and it is having major problems. Again, I have no money left, so I'm talking to lawyers, because from what I can understand from Tiger, it's a manufacturing defect, and now I have to pay Tiger tons of money (that I don't have) to fix something that shouldn't even be broken yet. (Warrenty still covered parts, but not labor.) Thankfully, Tiger comes through for me and I refrain from possibly taking legal action against manufacturers. On October 23rd, 2015, the coil gets swapped out. The technician thinks there might still be a leak somewhere, but nothing really comes of it. The parts are covered under warranty, Tiger is kind enough to waive the fee for labor. * * * * * The above gives Tiger five stars. I seriously had no money to pay them. I would have had to get a loan from somewhere. ...but... It is now July 18th, 2016, not even a year has passed since the installation of a new coil, and it is 74* in my house... I have the thermostat set at 70*. The temp coming out of the vents is around 68* - according to my meat thermostat. I have called Tiger, and we have an appointment for tomorrow. I fear that Tiger is going to tell me that I will need a recharged -- or new coils -- and I will have to pay them for service with money I still don't have. I'm praying everything still falls under a warranty. Pray for me, you all. I'll come update after my appointment and let you all know how it went. <3"

"Luis was absolutely phenomenal. He installed for us a 240volt connection in our garage for our electric car. He gave us the best price, was on time, very professional, and took the time to explain everything to us before and during the process of installation. Incredible, meticulous work. Thank you Luis."

"Apex installed a Whole Farm generator for my horse farm. They were very professional when they came to determine the size generator I needed and the quote was quite reasonable. The installation and hook up was completed in a timely manner. I now have peace of mind knowing that in the event of a power outage I can still provide excellent care to my horses. I will certainly be contacting Apex for my future electrical projects."

Generator Install questions, answered by experts

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.
